Sesame process is still running after the package was uninstalled i.e. there is no preuninstall hook which would stop it first. See bug 619102 for Cumin - it is the same type. sesame-0.7.3918-6.el5
See https://fedoraproject.org/wiki/Packaging/SysVInitScript#Initscript_packaging
Created attachment 442701 [details] Patch to RHEL5 sesame.spec
Spec file verified, I will wait for new packages to try if works.
Verified in sesame-0.7.4297-1.el5
